PQescapeByteaConn - returns wrong string for PG9.1 Beta3

<p class="MsoNormal">If<span style="mso-spacerun:yes">  </span>I use PQescapeByteaConn() for a conenction to a PG9.1
Beta3server, this function returns (e.g.) <strong style="mso-bidi-font-weight:normal">"\xea2abd8ef31...(and so
on.)..."</strong>.<pclass="MsoNormal"><p class="MsoNormal">Here the problem: there should be a second backslash in the
prefix.<spanstyle="mso-spacerun:yes"> T</span>he SQL Statement which uses this string (INSERT statement in my case)
returnswith an error ("Invalid byte sequence..."). If I add the second backslash manually everything works fine.<p
class="MsoNormal"><pclass="MsoNormal">When connecting to a PG9.0 server and using this function, the return value is
correct(with two backslashes): <strong style="mso-bidi-font-weight:       normal">"<a>\\xea2abd8ef31...( and so
on.)...</a>"</strong>.<pclass="MsoNormal"><p class="MsoNormal">This should be a bug in PG9.1 Beta3<p
